BINDING Thomas Roberts, Haverhill, Mass. Application March 1o, 1937, serial No. 130,058v f' s claims.

This invention relates to means and methods of binding or iinishing the edge of upper leather of shoes by what is commonly knownfas the French Cord process, in which a narrow ribbon, or galloon is stitched at one edge to the outer side of the upper, close to the edge ofthe latter and then is turned over the edge of the upper and adhesively secured to the inner side thereof beneath the lining.

It has become customary to reinforce the edge of the upper with a narrow textile' tape, which has usually been applied in one of two ways.

One method, which has been quite generally employed, consists in providing one side of the t'ape with a non-drying adhesive, by which it is attached to the inner side of the upper close tothe edge, and then adhesively attaching the portion of the galloon which is turned over onto the inner side of the leather to the outer surface of the tape,-the edge portion of thealloon having previously been provided with an adhesive, which is activated just before it is pressed against the tape. Another method is to provide both surfaces of the tape with the non-drying adhesive,

culties and are somewhat expensive on account of labor costs.

The Vobjects of my invention are to provide an improved method of applying the reinforcing tape, which will avoid the mechanical diillculties of previously employed methods, and which will enable the tapeto be applied without increase in labor costs, as compared with the costs when the tape is not employed, and will also enable a narrower galloon to be employed than previously, so that a saving in this respect may be made.

I accomplish these objects by providing a reinforcing tape, to one side of which a. non-drying adhesive has been applied, providing the sewing machine with a double guide through which the tape and galloon are simultaneously fed, respectively, and delivered to the sewing mechanism in such a position that one edge portion of the galloon will be fed onto the outer surface of the upper with its edge iiush with the edge of the upper, so that it may be stitched thereto in the 50 usual manner. At the same time the other edge portion of the galloon will be fed onto one edge portion of the adhesively coated side of the tape and pressed thereagainst, so that they become adhesively connected, after which the galloon will be bent over the edge of the upper and pressed so that when the edge portion ofthe galloon is against its inner side and the exposed adhesively coated edge portion of the tape will also be pressed against the inner side of the upper, so that it will become adhesively attached thereto,

and as the tape has alreadyvbecome adhesively 5 attached to the galloon, it will hold the galloon rmly against thev inner side of the upper. l

For a Vmore complete disclosure of my invention, reference is now made to the following specification, in connection with the accompanying drawing, in which:-

Fig. 1 is aA side elevationgof a portion of the sewing mechanism which is employed in per' forming a preliminary step of the'method.

Figs. 2 and 3 are respectively a 4sectional view and a front elevation of a guiding means whih is employed in connection therewith. l

Fig. 4 is a detail view illustrating the vrelative positions of the galloon and tape as they are fed onto the upper. i

Fig. 5 is a plan view of a portion of .the louter side of 'the upperafter the sewing operation has been performed. l

Fig. 6 is a sectional view at line BfS of Fig.v 5;

Fig. 7 is a plan view of the outer side and-y 25 Fig. 8` of theinner side of the upper 'after` the turning operation has been performed and "t f ,A Fig. 9 is a sectional view at line 9*-9 of Fig. 7.

In Fig. 1 of the drawing a portionof the sewing mechanism of a sewing machine is illustrated,-30

comprising the table I0, needle II, presser foot I2 i and a fixed portion I3 of the machine to which 'a guide I4 is attached, said guide having passages I5 and I6 through wiiich the galloony Il and tape I8 are fed, respectively. One side of the tape is cov.- ered with a coating of non-drying rubber adhesive I9, and both the galloon and tape are delivered to the sewing mechanism and onto the outer side of the upper l2l) in such a position that one edge of the galloon isflushwith the edge of the upper, to 40 which it is attached'by a rowl of stitches 2 I. The passage Iijthroug'hrwhichfthe' tape `is fed, is so arranged that it underlaps the opposite! edge portionofth' passage I5 from that'which guides the edge ofI the gallooiifi'n coincidencewith the edge corresponding 'edge portion' of the galloon and directly' onto. the upper. The. tape is passed. f through this passage'with its adhesively coated I .side uppermost, s'that, asthe tape and galloon -50 adhesivelycoated surface of the tape, `so that: 165555,

attached thereto, as shown in Figs. 8 and 9. The i tape is thus placed and secured in its reinforcing position and at the same time holds the galloon securely against the inner side of the upper. By a subsequent operation the tape'and inner portion of the galloon will be covered by the shoe lining in the usual way.

By thus attaching the tape tothe edge portion of the galloon, the effective width of the latterl is increased, so that in practice the width of the galloon which is employed may be decreased in width by one fourth, as compared with the width necessary when other methods are employed. A corresponding reduction in expense for galloon may therefore be secured.

It will be noted that the labor of attaching the galloon is not increased over the labor cost of attaching when the tapeV is not employed, so that the additional labor cost of applying the tapenecessary by previous operations is eliminated, as well as other items of expense.

The above described method also permits the application of a reinforcing tape to portions of the shoeupper to Vwhichit has not been practical to apply it by previously employed methods, as for example to narrow pointedlstraps. A

it will be understood that similar results may be secured by providing thesurface of the tape with any other form of Vactivated adhesive than 40 the non-drying rubber adhesive which is employed, thelatterbeing preferably employed for several reasons, principally because it is comparatively inexpensive and may be fed through a guide without danger rof clogging or other difficulty.

I claim: A v i. That method of applyinga reinforced binding to the edge portion of a shoe upper which consists in providing a binding ribbon and a reinforcing tape having one side coated with an activated adhesive, simultaneously feeding both the ribbon and tape onto the outer surface of the upper with the adhesively coated side of the tape uppermost and with one edge portion thereof underlying one edge portion of the ribbon and pressing the latter against the tape so that they become adhesively connected, sewing the other edge portion of the ribbon to the upper with their edges in coincidence and folding the ribbon over the edge of the upper and pressing it and the other adhesively coated edge portion of the tape against the inner side of the upper, adhesively to connect the tape thereto and hold the ribbon thereagainst.

2. That method. of applying a reinforced binding to the edge portion of a shoe upper which consists in providing a binding ribbon and a reinforcing tape having one side coated with a nondrying rubber adhesive, simultaneously feeding both the ribbon and tape onto the outer surface of the upper with the adhesively coated` side of the tape uppermostv and with one edge portion thereof underlying one edge portion of the ribbon and pressing the latter onto the tape so that they become adhesively connected, sewing the other edge portion of the ribbon to the outer side of the upper withits edge in coincidence with the edge thereof, and folding the attached ribbon over the edge of the upper and pressing' the other adhesively coated edge portion of the tape against the `inner side of the upper.

3. A reinforced binding on the edge of a shoe upper whichconsists of a ribbon having one edge portion stitched to the outer side of the edge portion of the upper and bent over its edge onto the inner side thereof, and a reinforcing tape having one side elated with a non-drying adhesive and having one edge portion overlying the edge portion of the ribbon on the inner side of the upper with its adhesively coated surface engaged therewithand with its other adhesively coated edge portion engaged with `the inner surface of the upper.
